Prefabricated reinforced concrete piece roof element - is suspended from top of furnace by vertical partially elastic ties

摘要

The prefabricated piece in reinforced refractory concrete is for making suspended roofs in industrial furnaces or other thermal appliances. It is cross reinforced and in the concrete part are ridges (1) below the cross frame (2). There are suspension holes (4) for carrying bolts (5), joined by vertical ties (6) symmetrical with a carrying plate (7). The suspension by bolts and ties allows vertical adjustment for height so that the load is level. The main tie (8) carrying the plate is made flexible vertically at its end by a spring element (9). Sealing of adjacent pieces is by cover plates.
